Product Details

MagnaFlow is well-known for its exhaust systems, and they bring that expertise to their direct-fit catalytic converters. If your 2016 or 2017 Mazda CX-9 is showing a check engine light related to emissions, this converter is designed to get you back on the road legally and reliably. It meets Federal/EPA requirements, so you can be confident it will pass emissions testing in most states.

This converter is built with high-strength 16-gauge 409 stainless steel tubing, which is highly resistant to corrosion and built to last. The internal design replicates the original equipment's flow dynamics, helping to maintain factory performance and fuel efficiency. MagnaFlow uses advanced 3D scanning during their research and development to ensure a precise fit, just like the original part. The single laser fusion weld is designed to minimize the chance of leaks, and its compact, low-mass design helps with thermal efficiency.

Installation is made simpler because this is a direct-fit unit, meaning no cutting or welding is required. It comes with essential hardware, including Torca Accuseal clamps, gaskets, and OE-sized hangers, so you have what you need to get the job done with the proper tools. This converter is compliant with legal standards for OBDII Federally registered vehicles with California or Federal/EPA Emission systems, but please note it is not CARB approved and cannot be shipped to California.
